Abstract (en)

[origin: EP0903525A2] A selective control device for a thermostatic valve, faucet and the like; the device comprises a control knob (14) connected to a housing cage (12) for a thermostatic sensor (13), which is screwed onto a central support (11); the thermostatic sensor (13) comprises an internal bellows (18) which operates on a resiliently yielding thrust member (17) connected to a valve closing member. A ring (35) for controlling rotation of the knob (14) is mounted in a rotatable and axially slidable manner along the edge of the knob (14) which is opposite to the side for housing the thermostatic element (13); the ring (35) is selectively engageable with and disengageable from the control knob (14) in a plurality of angular positions, in which suitable stop members (40, 41, 43, 44, 45) lock or allow rotation of the knob (14) through an angle having an amplitude corresponding to pre-set temperature values. <IMAGE>
